When choosing cutting fluid, we will choose cutting fluid according to the material, but sometimes we do choose the cutting fluid according to the material, and it is not very suitable to use. This may be due to different processing methods. Let’s take a look at how to choose aluminum alloy cutting fluid according to the processing method:
Aluminum ore resources are very rich and easy to recover. With the advancement of technology, its alloy properties are becoming more and more abundant. However, due to the soft texture and high plasticity of aluminum alloy, it is easy to stick to the tool during cutting, forming a built-up edge on the tool, and welding on the cutting edge during high-speed cutting, which makes the tool lose its cutting ability. Therefore, it is very important to choose aluminum alloy cutting fluid, not only to ensure good lubrication and anti-rust performance, but also to have good cooling and filtering properties.
1. High-speed cutting and drilling:
The high temperature heat generated during fast cutting, if the cutting fluid cannot take away the generated heat in time, the phenomenon of sticking will occur, which will seriously affect the machining accuracy of the workpiece. Therefore, the cutting fluid should be a cutting fluid with good lubricity and excellent cooling performance.
2. Fine grinding and super fine grinding:
A lot of heat will be generated during the grinding process, and the grinding debris under grinding is very small, so when choosing a cutting fluid, the filtering performance and lubrication performance of the cutting fluid must be considered at the same time. If the viscosity of the selected cutting fluid is too high, the grinding debris cannot be deposited or filtered in time, and the surface of the workpiece will be scratched as the cutting fluid circulates to the processing area. Therefore, when fine grinding or super fine grinding, low-viscosity grinding fluid or cutting fluid with precipitation should be selected.
3. Ordinary low-speed grinding or cutting:
The requirements for machining accuracy are not too high, ordinary cutting fluids can meet the needs of production, and products with good cleaning and cooling properties can be selected for use. If conditions permit, it is best to choose a special aluminum alloy cutting fluid. Since the special aluminum alloy cutting fluid generally contains special aluminum inhibitor, it can ensure that the surface of the workpiece will not be damaged during the machining process.
